During yesterday’s commemoration of the fall of the Berlin Wall as well as the fall communism throughout the Eastern bloc, Poland’s role and impact was prominently displayed.

The last two decades have resulted in sweeping political and economic transformations, culminating in NATO and EU membership. However, once the euphoria and self-congratulatory back-patting subside, what will be the next chapter in Poland’s modern history? How will Poland’s geopolitical role evolve over the coming decades? What are the key challenges facing Poland, both domestically and within a maturing European Union?

According to many leading experts, Poland is in its best geopolitical position in 300 or even 400 years, but simply does not know how to take advantage of it. Three key issues will test Poland in the near-term: energy security, economic sustainability and relations with its eastern neighbors. How it chooses to address these challenges will determine whether Poland lives up to its potential as an emerging mid-size European power or instead follows the path of some older and stagnant EU members.

Regarding energy security, Poland needs to maintain diversity of energy options, both in its sources and suppliers. It also needs to ensure that its energy sector maintains fair competition as well as free and open markets. By encouraging the EU to develop a southern energy corridor (beyond Nabucco), Poland and the rest of Central Europe will be able to simultaneously address fallout from the global economic crisis and impeding climate change.

Economically, Poland’s greatest hindrance is its low labor participation, due to high levels of early retirement. This will not only threaten future competitiveness, but will create enormous strains on the social welfare system. Poland needs to build off of the legacy of Solidarity and the success of previous market reforms by reinvesting in building a viable civil society and strong social (entrepreneurial) capital. This will not only deepen economic convergence within the EU, but create a set of best practices for other aspiring EU accession countries.

Finally, Poland’s relations with its eastern frontier (Belarus, Georgia, Ukraine, etc.) will play an increasingly critical role in Europe’s future common foreign and security policy. While the Eastern Partnership (EP), is neither a substitute for nor a guarantee of EU membership, the EU, and especially Poland, should play a bigger role in encouraging EP countries to speed up the pace of reform and meet EU laws and standards. By acting as a bridge between the Western EU members and the EP, Poland can not only share its own accession best practices, but enable EP countries to fortify their domestic security through greater political and economic cooperation with Europe.

As the dust settles on the battered economies of Central Europe, winners and losers have clearly emerged on this the one-year anniversary of the global financial crisis.

Poland, along with the Czech Republic and Slovakia, stand ahead of the pack due to prudent economic policies, manageable current account deficits and lower macroeconomic imbalances (including lower levels of indebtedness).

Romania's and Bulgaria's growth prospects, which face stiff competition from healthier CEE economies, will continue to be burdened by deep political and economic deficiencies. Unless major initiatives, both at the local and EU level, address chronic corruption and structural asymmetries, the two countries are headed for stagnation.

Finally, the Baltic States and Hungary, saddled with debt and strict austerity programs, have the toughest road ahead and the least amount of flexibility in their recovery programs.

Despite their various predicaments, Central Europe has the opportunity to emerge stronger and more economically viable. The key is to learn from previous mistakes (domestic, US and wider EU), resist reform fatigue and continue to converge with the EU-15. That responsibility must not rest solely on Central Europe.

The EU, particularly its wealthier members, must ensure that Central Europe continues to be deeply anchored in market principles and EU institutions. Most importantly, they must convince the region that they are critical players in Europe’s overall recovery and prosperity.

For Poland, the best path forward includes keeping public spending low, taking advantage of EU funds for major reforms (healthcare, education, infrastructure and business climate) and setting a date for euro entry that is most favorable to its economic development.

Most importantly, Poland must refrain from excessive expansionary fiscal policies. Not only will Poland be unable to afford the extremely high interest rates required to cover the cost of borrowing, it will further delay euro entry.

Instead, Poland should accelerate critical structural market reforms to gain a competitive edge, before the window of opportunity closes.
